To all whom it may concern} Be it known that I, Amman. eocn' m,

a c itizenof the United States, residing at Ripon, countyof S an J oaquin, State of Gali fornia, have invented certain new' and useful Improvements in Antifriction Clips for be a'fnll, clear, and exact description of the same, reference being'h'ad to the accompanyingdrawings, and to the Characters of referen'ce marked thereon, whichfform a part of this application. V

This invention relates toliinprovements in the common form of mowing devices used in connection with v various kinds 'of I agricultural machinery. Such devices comprise a finger bar carrying the stationary cutters and guards, andfla reciprocating knife-bar carrying knife blades; slidably supported on the stationary cutters of the guard fingers. As usually mounted, the knife-bar bears directly'against the flat edges of wearing plates fixed on the finger bar, resulting in a severe drag being placed on the driving mechanism and causing rapid wear of the contacting surfaces, making frequent renewal of the wearing plates necessary.

The principal object of my invention is to eliminate the above objectionable features by providing roller bearing means for the knife bar arranged so that there is no wearing contact between the finger and knife bars, and the knife-bar will run very much easier than at present.

Another object is to construct my rollerbearing mounting meansin such a way that they take the place of the usual knife clips,

' and are secured onto the finger bar by using the same bolts as are now used in holding such clips.

My device may be properly considered as an attachment, applicable to all standard mowers without requiring that any structural alterations bemade thereto.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views:

Fig. 1 is a top fragmentary outline of an clip, detached} j Referring now 'more, particularly 'to'fithe characters of reference marked on the drawings, the numera'hl"denotes a fingerbar,

- i Fig.- 3 is perspective View of the roller I having forwardly projecting guards 2 on which are the ledger plates or fixed cutters 3. Positioned between the ledger platesand the finger bar is the knife bar 4,.having the usual knives 5 secured thereon by rivets 6.

' The'knives overhang the j-rear edge of the bar 4'somewhat, certain ones resting on wearing plate 7 Imounted on the-"finger bar at suitably spaced intervals. The parts thus far described arestandard, and I do not lnterfere with the same when applying my attachment thereto. a

The latter comprises a'plurality of plates 8, one for each of the wearing plates, and having slotted holes 9 to aline with the bolt holes in said wearing plates. The samebolts 10 employed in securingthewearing plates and the guards thereunder, to the finger bar, are used in securing the plates 8. 'The latter are bent upwardly at their rear ends for a certaindistance, and are then bent lower portions 8, as shown at 11. The forward extremities of the upper portions 11 are then bent down as at 12 to engage and form guides for the knives and prevent upward movement thereof, in the same manner as is done by the usual clips, which my The forward edges of the rollers bear against short tracks 16 fixed on certain ones of the knives 5 by means of rivets 17 passed. through the same holes already in the knives The length of these tracks,

and knife bar. is sufiicientto allow of the reciprocation of the knife bar through its usual extent of travel without the rollers leavingsaid tracks, and theyare so disposed that when bearing against the rollers, the adjacent edges of the knife bar and wearing plates are free of each to extend horizontally over and beyond the as I - direction which enables the clips to be moved to and from the tracks.

From the foregoing description it will be readily seen thatI have produced such a device as substantially fulfills the objects of the invention as set forth herein,

While this specification sets forth in detail the present and preferred constructionof the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims Having thus described my invention what I claim as new and useful and desire t secure by Letters Patentis:

1, A unitary attachment for mowing machines having a finger bar, a cutter bar, and

r a bearing member mounted on the cutter bar; including a clip adapted to be secured to the finger bar, and a bearing member contained within the clip and projecting beyond one end thereof to frictionally engage the bearing member on the cutter bar.

2. A unitary attachmentifor mowing machines having a finger bar, a cutter bar, and

a bearing member mounted on the cutter bar; including a clip adapted to be secured to the finger bar, and a pivoted bearing member mounted in the clip and projecting beyond one end thereof to frictionally engage the bearing member on the cutter bar.

a bearing member mounted on the cutter bar; including a U-shaped clip adapted to be secured to the finger bar, a bearing member contained within the clip and projecting beyond one end thereof to frictionally engage the bearing member on the cutter bar; one side of the clip projecting beyond said cutter-bar bearing member and being bent to engage and guide the knives of the cutter bar. i

In testimony whereof I aifix my signature. ALFRED D. GOODWIN.
